An underground economy for unlicensed slimming medications is propelled by social media fitness personalities and sellers on communication apps, according to new investigations.
Retatrutide, which remains in clinical trials, is being promoted by social media influencers for its supposed weight-reducing properties. Viewers are encouraged to message these accounts directly for source information, while also receiving promotional offers.
Additionally, a flourishing market exists on messaging services, where communities with numerous of members share comparison photos, administration instructions and claims of rapid UK delivery. Vendors promote the drug there before directing customers to WhatsApp for purchases.
Retatrutide is an experimental injectable developed by American pharmaceutical company Eli Lilly. The treatment targets three gut hormones – glucagon-like peptide-1, GIP and glucagon. Preliminary studies indicate it could assist individuals lose up to 25% of their body weight. Nicknamed the “triple G”, the drug is being promoted digitally as the next Ozempic.
However, physicians and chemists have warned that the distribution of what remains an unlicensed medication in the United Kingdom is a cause for concern and could result in individuals administering products of unknown origin.
Several experts stated the popularity for the experimental drug could be connected to the increasing cost of licensed weight loss treatments such as Mounjaro.
Selling retatrutide on social media or messaging apps is illegal in the UK, as it is an unapproved medication that must not be marketed or supplied for personal consumption under the British medical regulations.
Some content creators try to circumvent the rules by referring to the drug as a “research chemical” or citing it as “not for human consumption”. Retatrutide is not a controlled substance, but promotion and supply can still breach medicines, marketing, and customer laws, potentially leading to fines, legal action or prison.
According to the social media company, the service has taken down problematic content and prohibited related hashtags and search suggestions. The organization said it was dedicated to maintaining the service safe and allocating resources in strengthening enforcement strategies.
Investigations also found groups with up to 9,000 participants marketing the experimental drug using the platform's integrated discovery tool, which operates like a online catalog. Entering “retatrutide” immediately displays groups with thousands of members, populated with photos of slimming results, glowing reviews and detailed guides for mixing or administering at home.
After minutes of joining one group, a seller posted contact information, where most purchases take place. The vendor provided an guidebook and promised delivery within 48 hours. When questioned whether the product was authentic, one seller said: “You can’t be sure.” Another provided a image of a supposed laboratory certificate. Not one asked about weight, medical conditions or past usage.
Within these communities, posts show black plastic packages with postal service labels, stating to include fresh supplies. One message read: “It took eight of us to load them this morning.”
Buyers can select between dry substance containers, prepared at home with sterile water, or ready-to-use injectors usually priced at 160 pounds for 20 milligrams. When asked how much time a injector should be used, sellers give conflicting answers varying between a several days to “depends on your body”.
A spokesperson for the messaging service stated it actively moderated dangerous material on its service including material that promoted the “misuse of controlled medications”. The company noted that it eliminated “millions of pieces of harmful content each day”.
“People are administering materials they can’t verify. Even if the science behind this drug is valid, these digital products may not contain what they advertise,” said Jason Murphy, the head of pharmaceutical services at Chemist4U.
Dr Crystal Wyllie of an online medical service connected the increase in demand to current price rises for authorized weight-loss medications such as Mounjaro. “With costs increasing, individuals are turning to online platforms. But fake treatments are highly risky. You can’t be certain what’s contained or whether the conditions they were produced in was clean,” she explained.
Her staff has already seen patients injured by self-injection from unconfirmed sources. “We understand the frustration, but buying from messaging apps or communication platforms is gambling with your well-being,” said the doctor. “These substances could be impure or improperly measured.”
A representative from the pharmaceutical company said the substance was in phase 3 clinical trials and had not been reviewed or approved by any regulatory agency anywhere in the world. “Therefore at this time no one can market [it] for personal consumption,” they explained, adding that any product “misleadingly claiming itself as a Lilly investigational product not yet approved … may subject users to potentially significant medical dangers”.
